HAND STAMP.

Application filed November 20, 1928. Serial No. 320,740.

My invention relates to hand stamps, in which characters are made to contact with an inking pad so that after being released from cont-act therewith the characters may be stamped or printed upon a suitable surface, and it concerns particularly an improvement in a self-inking hand stamp, for which a United States Patent, No. 1,547,410, was granted to me on July 28, 1925.

In this patent, I disclose a hand stamp of such a construction as to cause the inking pad to swing to the side of the frame structure that holds the character-exposing mechanism therein, by a manual'pressure upon a push button in a handle connected with the frame, and to cause the pad automatically to resume its engagement with the exposed characters when the manual pressure upon the push button is released. Although the hand stamp disclosed in this patent thus represents a decided forward step in the art, it has certain defects, which, however trivial, still maybe objectionable to some of the stamp-using public.

One of these defects is that the inking pad engages the exposed characters with a sidewise and brushing movement, thus subjecting the pad as well as the exposed characters to wear by each movement of the pad and also, by the frictional engagement of the pad with the characters, retarding the movement of the pad to its normal, fully registering position relative to the exposed characters when the stamp is not in use. Another defect is that, because of not having any locking means provided therefor, the inking pad, by careless handling, may be temporarily thrown out of engagement with the exposed characters and made to remain,

in such a non-engaging position, so that, if an attempt is made to print with the stamp, the exposed characters will not be printed or only partly printed upon the desired surface until the pad has been allowed to return to its normal position in which it fully engages the characters.

One object of my present invention is to construct a hand stamp so that the inking pad has a terminal sliding movement toward, or an initial sliding movement from, the exposed characters in the stamp, while the remainder of. the pads movement is oscillative, thus entirely avoiding a frictional movement over the characters and thereby prolonging the life of the stamp and causing the stamp to be quickly and easily operated.

Another object of the invention is to hold the inking pad normally in engagement with the exposed characters and to lock the inking pad in its normal position.

A further object in the invention is to provide the stamp with means for stopping the swinging movement of the inking pad when the pad is in the sliding position, thus eliminating unnecessary movements of the inking pad and making the stamp positive 1n its operation. I

Still further objects and advantages will appear from the following detailed description, illustrated in the accompanying drawing, in which 1 Figure 1 is a side elevation of a ban stamp constructed in accordance with my I present invention, the view showing the inkmg pad in its normal position, and dotted lines indicating how the stamp is held between the fingers of a persons hand preparatory to the operation thereof;

Figure 2 is an elevation taken from the.

right of Figure 1 and also showing the inking pad in its normal position, the view belng partly in mid-section and partly broken in order to disclose more clearly the in-' terior construction; and

Figure 3 is an elevation similar to Figure 2, but on a reduced scale, and showing the operating handle depressed and the inkin pad swung thereby to its extreme latera position.

The hand stamp of my present invention includes a frame 1, comprising a base member 2, two forks or lateral members 3 extendin virtually right-angularly from the ends 0 the base member, and an end member 4, which is Virtually right-angularly joined to the ends of the lateral members. In the forks or lateral members 3 is mounted a shaft 5, which preferably extends outside of the members and is reduced at its ends so as to form pivots 6. Upon the shaft 5 within the frame 1 is mounted a series of drums 7, each of which is provided with a customary operating disk 8, and over the respective drums and the end member 4 are stretched endless belts 9, upon the outer surfaces of which are formed printing characters 10 adapted to be exposed upon the end member 4 in any desired combination for printing or stamping on a suitable surface, the forks preferably tapering toward the end member 4 so as not to extend beyond the outer surfaces of the belts.

Thelbase member 2 is preferably slott d longitudinally as shown at 11, and slots12 with a central, fiat-bottomed bore 14, which at its bottom and at the end of the handle towardlthe base member connects'with a central bore 15 of a smaller diameter. the larger bore his loosely fitted a push button-l6, tothe inner end of which one 15 end of an element in the form of a rod 17, ingaxialealigninent with the push button, is connected, while the other end of the rod is centrally connected with the base member 18 ofia oke 19, which is adapted to embrace 90::theifoijks 3, of the frame 1 with its branches QOandto engage the side edges of the slots 12 with the base member so as to allow asliding and'oscillative movement of the yolie, the elemental? and the push button 16; coil splt-ingfllareundthe element 1'? in the bore 14 is adapted to force the push button outwardrand theyohein the direction ot the base; member 2 of the frame 1.

In iord erto allow a swinging movement of theinking pad 22, the pins 31 are arranged so as to be out of alignmentwith the Pivots 6 and the pins 30,.and the branches 20 of the "yokeil9 are preferably offset, as shown at 32, and each of the slots 12 has one of its side edges curved, as shown at 33. theyswinging movement of the inking pad, tllSrCllI'VQd portions 33 of the slots 12 allow the haseiinember 2 of theframe l to respond Thus, during to the oscillative impulse as determined by the eccentric relations of the pins 31 to the pivot 6, while he push button 16 by its loose the bore 1% is free to follow the oscillative movement, is also the element 1?,which may have a portion 3a of its side out out in order to clear the ct of the bore i l.

ll hen it desired to use the stamp, the operator preferably grips the handle 13 thereof with two fingers ofone hand, while with the thumb he depresses the push :button l6, as indicated by dotted lines in Figure 1. movement ofthe inking pad will boa direct push ' snownin Figure 3, th oper his finger grip onthe handle nting the exposed characters face. he I relea. his

ltshouldbe observed that, although for the sake of convenience l have shown the pivots it 6 as being at the ends of the shaft 5 on which the drums '7 are mounted, such pivots may he arranged in other convenient I l, and the arrangement f the'other' parts of the stamp may becorrespondingly modified in order that t ie operation ofithe stamp may be eiii'ected in a manner similar to that already t escribed.

It is also evident that, as thewinking pad eventually wears, the wear is automatically taken up by the pads sliding movement toward the exposed CllttllCtGl'Ss: The base-men1- her 1530f the yoke 19 is for this reasonailewedv i pad has been swung to e pusl'i button the spring 2i on the contactof theive siue edges of the slots, therebv 119 :es 011- the 120 to slide freely within theslot 11 and toward the handle 13, as is understood from the disclosure in, Figure 2.
